Bosch Performance Line CX Motor
The Reaction Hybrid Pro 800 is powered by a Bosch Performance Line CX Smart System drive unit from the BDU38 family. Its responsive pedal assistance helps riders manage hills, rougher paths and changing gradients while retaining the natural involvement of cycling.
Das Radhaus specifies a maximum torque of up to 100 Nm for this 2026 configuration. Available motor output can depend on installed software and settings, so higher torque figures should not be guaranteed without checking the delivered system.
The Bosch Purion 200 combines a compact display with convenient assistance controls, allowing riders to view essential journey information from the handlebar.
800 Wh Battery & Range
The integrated Bosch PowerTube 800 battery provides 800 Wh of rated energy capacity. Its position within the aluminium down tube helps maintain the bicycle’s streamlined appearance while supplying energy to the Bosch motor.
The standard specification includes a Bosch 2A charger. The frame is also compatible with the optional Bosch PowerMore 250 range extender, sold separately.
Actual riding range depends on assistance settings, gradients, rider weight, luggage, temperature, tyre pressure and trail conditions. No guaranteed distance per charge is provided for every riding scenario.
Shimano XT and Deore 12-Speed Gearing
The bicycle features a Shimano XT RD-M8100-SGS rear derailleur combined with a Shimano Deore SL-M6100-IR shifter.
A Shimano Deore CS-M6100 10–51T cassette provides a wide range of ratios for hill climbing, flatter sections and varied riding conditions. A KMC e12 chain and ACID MTB Hybrid Pro 38T crankset complete the drivetrain.
Air Suspension & Braking
The SR Suntour X1-32 LO-R Air fork absorbs bumps from uneven surfaces and provides adjustable air-sprung suspension.
The size S frame features 100 mm of front suspension travel, while sizes M through XXL offer 120 mm.
Shimano BR-MT420 four-piston hydraulic disc brakes, combined with 203 mm rotors at both wheels, provide controlled stopping performance for recreational trail riding and everyday cycling.
Wheels, Tyres & Handling
ACID SLX 30 tubeless-ready wheels are paired with Schwalbe Smart Sam Active 2.6-inch tyres. This setup offers a balance of traction and versatility on appropriate gravel tracks, forest routes and paved surfaces.
CUBE’s Size Split approach uses 27.5-inch wheels for size S and 29-inch wheels for sizes M, L, XL and XXL.
The Aluminium Superlite frame uses Agile Ride Geometry to combine stable handling with responsive steering.
Comfort & Frame Design
The frame incorporates Gravity Casting Technology, Boost148 rear spacing, advanced internal cable routing and integrated battery storage.
A CUBE Rise Trail Bar 35, ACID Hybrid Perform grips and ACID Sequence 160 saddle create practical contact points for everyday and recreational riding.
The CUBE dropper seatpost allows riders to lower the saddle for descents and raise it for comfortable seated climbing, using a convenient handlebar-mounted lever.
Accessory Compatibility
The standard Reaction Hybrid Pro 800 is supplied without the fully equipped commuting package. Compatible mudguards, a luggage carrier and kickstand can be fitted using the frame’s designated mounting points.
An X-Connect interface supports a compatible ACID front light, available separately. The optional Bosch PowerMore 250 range extender can also be added where compatibility and installation requirements are met.
